In racing SIGMA slipper clutches have proven themselves to be a reliable and effective addition to many a racing teams armoury. On their very first outing in a Ducati back in 1998 they won a World Superbike support race at Donington and in 2004 at Brands Hatch won their very first British Supersport race on Jay Vincent's Padgett's CBR 600. Since then they have won many BSB Supersport races and championships and a bunch of TT’s and North West 200 races.
